name : get-key-policy.rst **To copy a key policy from one KMS key to another KMS key** The following ``get-key-policy`` example gets the key policy from one KMS key and saves it in a text file. Then, it replaces the policy of a different KMS key using the text file as the policy input. Because the ``--policy`` parameter of ``put-key-policy`` requires a string, you must use the ``--output text`` option to return the output as a text string instead of JSON. :: aws kms get-key-policy \ --policy-name default \ --key-id 1234abcd-12ab-34cd-56ef-1234567890ab \ --query Policy \ --output text > policy.txt aws kms put-key-policy \ --policy-name default \ --key-id 0987dcba-09fe-87dc-65ba-ab0987654321 \ --policy file://policy.txt This command produces no output.
